1. A method for displaying a multi-primary color system, comprising:
providing a set of image data including a set of primary color signals, wherein the set of primary color signals corresponds to a set of tristimulus values in XYZ color space;
creating an updated set of primary color signals from the set of tristimulus values in the XYZ color space and at least one primary triad;
providing at least one pseudo white point with the set of primary color signals based on the at least one primary triad in the XYZ color space;
creating an updated set of hue angles for the updated set of primary color signals using a set of saturation data included in the set of image data, wherein the updated set of hue angles includes inverted hue angles;
converting the set of image data for display on at least one display device using the updated set of primary color signals; and
sending the converted set of image data to the at least one display device for display;
wherein the multi-primary system includes at least four primaries.
